Once connected it works great but it's hard for this bulb to get connected and keep connected. First, there is this issue of this bulb getting connected on 2.5 GHz frequency only WiFi. Unaware of this, I tried first to get it connected to my WiFi which had automatic selection between 2.5 GHz and 5GHz frequency and it didn't work. After that, even when I separated WiFi channels, it took a hard reset of the bulb to get it to connect to the 2.5GHz channel. And then, all of a sudden, after a few days it lost the connection and wouldn't connect! Reset it again, kept trying but no luck. I realised then that even if I somehow get it connected again, I'll be dealing with all the same issues for a long time to come. So, one bulb tried and another yet to be opened, returned both of the items back to Amazon.
